Hello Lon the rest of the list - You responded the other day that my problem with the ext3 volume mounting up on multiple nodes might be related to this bug listed. Support looked over my config and explained to me that I nested my resources when I really shouldn't have. They say the cluster

Interesting, thanks. I'll mention this to support. I'm sure they can find other ways to improve my increasingly ugly config though too! Josh On 10/31/07 12:55 PM, Lon Hohberger [EMAIL PROTECTED] wrote: On Wed, 2007-10-31 at 11:56 -0600, Josh Gray wrote: Hmmm I don't see to have access to
